The point is that in other threads, debates and issues that are discussed and posited here and elsewhere, the attempted rationale for taking one side or another of an given argument is related to the belief in a personal god. Most often, in Western discourse, it's the belief in a Christian god.

My challenge is to posit what good reasons there are to believe in such a god. With these reasons not forthcoming, it would stand, therefore, that there are no good reasons for believing in a god. This conclusion then becomes a premise leading to the next conclusion which is belief in one or more gods is irrational.
